If You Missed It inParis and in Urbana …An Exhibit of the Worksof Siméon-Denis PoissonYvette Kosmann-Schwarzbach

From the Poisson exhibit at UPMC in Paris. TheTraité de Mécanique (1833) is open to the page

where he recalls that he “had proved theproperties [of the Poisson brackets] in a direct

Everyone has heard of the Poisson distribution, ofthe Poisson brackets, and of many other “Poissonsomethings.” But who was Poisson and what didhe do to acquire such fame? At the initiative ofits director, Brigitte Laude, the research library,“Mathématiques Informatique Recherche” (MIR), ofthe Université Pierre et Marie Curie in Paris, onthe Jussieu campus, organized an exhibit, “Siméon-

Denis Poisson. Les Mathématiques au Service de laScience,” which was on display from 19 March to19 June, 2014, aiming to present some of Poisson’sworks and their modern continuation.

From Poisson’s baptism certificate, drawn up oneday after his birth in Pithiviers (a small town southof Paris); to the list of students admitted to theÉcole Polytechnique in year 7 of the Republic, wherehe is no.1, at the top of a finely written page; to thepostcard representing his statue erected in 1851in his native city, eleven years after his death, wefollow Poisson in his brilliant career as a professorat the École Polytechnique (he was appointed atthe age of twenty-one to be the successor toFourier), later at the Faculté des Sciences (since itscreation, in 1809), and, after 1812, as an influentialmember of the Académie des Sciences. Poissonnever travelled, but his works did. Several of hisbooks and articles were translated into German andinto English, influencing the British mathematicalphysicist George Green among others.

All Poisson’s BooksBetween 1799, one year after his admission to theÉcole Polytechnique at the age of seventeen, andhis death in 1840, Poisson wrote approximately200 memoirs, articles, notes and reports, and tenbooks. Not long before he died, he drew up acareful catalogue of his published works. The ideaof the exhibit at Jussieu was primarily to presentthe original editions of all his books, and thatwas almost achieved. Two books, the first versionof the mechanics course he taught at the ÉcolePolytechnique and a slim, technical volume on theeffect of firing a cannon, had to be representedby scanned copies of the title pages.

two volumes of his 1811 Traité de Mécanique, intheir fine leather binding with spines decoratedin red and gold, on loan from an anonymousprivate collection, were displayed and, next tothem, his “considerably enlarged” second edition,open to page 399 where he cites Lagrange “whoextended the method of variation of arbitraryconstants to all the problems of Mechanics” andrecalls that he had found and published [in1809] a direct way to determine the inverses of theexpressions that had been found by Lagrange…thatis, he had discovered the “Poisson brackets”! Hisfamous Recherches sur la probabilité des jugements(1837) was open to page 206, where one reads

P = (1+ω+ ω2

books and memoirs dealt with his contributions to,among other branches of mathematics and physics,the analysis of integrals and series, differentialequations, integration in the complex domain, aswell as to the theories of electricity and magnetism,heat, capillarity, elasticity, optics, all of whichhe expected to include in a “Traité de physiquemathématique” that he would not be able tocomplete before his death at the age of fifty-eight.

The rest of the exhibit contained contemporaryand later evaluations, laudative or critical, ofPoisson’s role in the development of mathematicsand physics in the first half of the nineteenthcentury, and a selection of modern books in whichPoisson’s work is extended: texts and researchmonographs on potential theory, probability theory,Poisson geometry in mathematics and physics.

Urbana-Champaign, August 2014A near duplicate display was re-created by TimCole, Mathematics and Digital Access Librarianat the University of Illinois in Urbana-Champaign,and the librarians at UIUC on the occasion of the“International Conference on Poisson Geometry inMathematics and Physics” (Poisson 2014) organizedby Rui Fernandes and Eugene Lerman. The exhibit,entitled “Siméon-Denis Poisson. Mathematics inthe Service of Science,” was on display in theMathematics Library at Urbana, August 4–14, 2014.

Berkeley: Another Chance?If you missed the Paris exhibit, and then again theUrbana exhibit, you may still have a chance to seeit! In fact, at the initiative of Alan Weinstein andDavid Li-Bland, organizers of “Gone Fishing 2014,”November 8–9, 2014, this exhibit will be re-createdin the Library of the Mathematics Departmentof the University of California in Berkeley. Theinauguration is scheduled for November 7, 2014,and the exhibit will be on display November 7through December 17.

From the exhibit at UIUC in Urbana-Champaign.Displayed are articles by Poisson published inthe Journal de l’École polytechnique between1801 and 1823.

If you do not plan to travel to Berkeley forthe occasion, below are the websites where youcan download the Paris catalogue in French or inEnglish translation as well as the Urbana catalogue,both of which contain short essays on some of theitems that were displayed.

The librarians wish to thank all the institutionsthat lent material for these two exhibits.
